2008-07-08vlan: avoid header copying and linearisation where possiblePatrick McHardy
- vlan_dev_reorder_header() is only called on the receive path after calling skb_share_check(). This means we can use skb_cow() since all we need is a writable header. - vlan_dev_hard_header() includes a work-around for some apparently broken out of tree MPLS code. The hard_header functions can expect to always have a headroom of at least there own hard_header_len available, so the reallocation check is unnecessary. - __vlan_put_tag() can use skb_cow_head() to avoid the skb_unshare() copy when the header is writable.

2008-07-08vlan: TCI related type and naming cleanupsPatrick McHardy
The VLAN code contains multiple spots that use tag, id and tci as identifiers for arguments and variables incorrectly and they actually contain or are expected to contain something different. Additionally types are used inconsistently (unsigned short vs u16) and identifiers are sometimes capitalized. - consistently use u16 for storing TCI, ID or QoS values - consistently use vlan_id and vlan_tci for storing the respective values - remove capitalization - add kdoc comment to netif_hwaccel_{rx,receive_skb} Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2008-07-08vlan: move struct vlan_dev_info to private headerPatrick McHardy

2008-07-08vlan: uninline __vlan_hwaccel_rxPatrick McHardy
The function is huge and included at least once in every VLAN acceleration capable driver. Uninline it; to avoid having drivers depend on the VLAN module, the function is always built in statically when VLAN is enabled. With all VLAN acceleration capable drivers that build on x86_64 enabled, this results in: text data bss dec hex filename 6515227 854044 343968 7713239 75b1d7 vmlinux.inlined 6505637 854044 343968 7703649 758c61 vmlinux.uninlined ---------------------------------------------------------- -9590 Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2008-07-08vlan: fix network_header/mac_header adjustmentsPatrick McHardy
Lennert Buytenhek points out that the VLAN code incorrectly adjusts skb->network_header to point in the middle of the VLAN header and additionally tries to adjust skb->mac_header without checking for validity. The network_header should not be touched at all since we're only adding headers in front of it, mac_header adjustments are not necessary at all.

2008-07-05net-sched: sch_htb: remove write-only qdisc filter_cntPatrick McHardy
The filter_cnt is supposed to count filter references to a class. Since the qdisc can't be the target of a filter, it doesn't need a filter_cnt. In fact the counter is never decreased since cls_api considers a return value of zero a failure and doesn't unbind again. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-05net-sched: sch_htb: remove child and sibling listsPatrick McHardy
Now that the qdisc isn't destroyed in hierarchical order anymore, the only user of the child lists left is htb_parent_last_child().

2008-07-05net-sched: sch_htb: move hash and sibling list removal to htb_deletePatrick McHardy
Hash list removal currently happens twice (once in htb_delete, once in htb_destroy_class), which makes it harder to use the dynamically sized class hash without adding special cases for HTB. The reason is that qdisc destruction destroys classes in hierarchical order, which is not necessary if filters are destroyed in a separate iteration during qdisc destruction. Adjust qdisc destruction to follow the same scheme as other hierarchical qdiscs by first performing a filter destruction pass, then destroying all classes in hash order.

2008-07-05net-sched: add dynamically sized qdisc class hash helpersPatrick McHardy
Currently all qdiscs which allow to create classes uses a fixed sized hash table with size 16 to hash the classes. This causes a large bottleneck when using thousands of classes and unbound filters. Add helpers for dynamically sized class hashes to fix this. The following patches will convert the qdiscs to use them. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2008-07-05vlan: Add GVRP supportPatrick McHardy
Add GVRP support for dynamically registering VLANs with switches. By default GVRP is disabled because we only support the applicant-only participant model, which means it should not be enabled on vlans that are members of a bridge. Since there is currently no way to cleanly determine that, the user is responsible for enabling it. The code is pretty small and low impact, its wrapped in a config option though because it depends on the GARP implementation and the STP core.

2008-07-05vlan: Move device unregistration before lower dev cleanupPatrick McHardy
